Android Show DropDown Menu on MenuItem click

Question

I want to show DropDown menu on MenuItem click just like this.

Answer 1

what about showing popup menu when clicking onthat item ? here is the code :

 @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();



        if (id == R.id.action_notifi) {
        // here we show the popup menu
        popup();
        }

        return super.onOptionsItemSelected(item);
    }


    public void popup(){
          PopupMenu popup = new PopupMenu(MainActivity.context, v); //the v is the view that you click replace it with your menuitem like : menu.getItem(1)
                    popup.getMenuInflater().inflate(R.menu.medecin_list_menu,
                            popup.getMenu());
                    popup.show();
                    popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                        @Override
                        public boolean onMenuItemClick(MenuItem item2) {

                            switch (item2.getItemId()) {
                                case R.id.Appeler:
                                 //do somehting

                                    break;
                                case R.id.EnvoyerMsg:
                                 //do somehting

                                    break;
                                case R.id.AfficherDet:
                            //do somehting

                                    break;
                                case R.id.Afficher: 
                        //do somehting
                                    break;
                                case R.id.AvoirRdv:
                              //do somehting
                                    break;

                                default:
                                    break;
                            }

                            return true;
                        }
                    });

                }
            });
    }

and here is the medecin_list_menu (my menu)
